FAMILIAR TREES AND THEIR LEAVES. 



Boston Common was cut down several years ago on 

 account of its decayed condition. The wood of the 

 elm is white, exceedingly tough and durable, and 

 is used to make wheel-hubs, yokes, and saddle-trees ; 

 it is even beautiful when used in cabinet work, and 

 has a rich, light yellow-brown color far superior 

 to that of the birch. The tree is common 

 in all parts of the country. The English 

 elm ( Ulmus carrvpestirii) has a leaf which 

 is smaller and darker than 

 that of our own elm, and it 

 is not infrequently rough ; 

 g^jf its shape is also more ab- 

 ruptly sharp -pointed. The 

 limbs of the English elm 

 grow out from the trunk at a 

 wide angle, and they are apt to give the 

 tree an irregular outline with a larger 

 upper and a smaller lower mass of 

 foliage. There are numbers of fine 

 old English elms on the Common 

 in Boston ; but few of them 

 reach a height of over 50 feet. 

 Corky White Elm. The corky white 



Ulmus racemosa. e ] m (gQ to 10 Q 



feet high) resembles the white elm, with this very 

 pronounced difference : its branches are marked 



Corky White Elm.
